http://www.nwoods.com/sanscript - a GraphicalProgrammingLanguage based on DataflowProgramming for WinXX.
"Sanscript literally allows you to draw your application, not code it. You drag a component to the canvas, and wire it to the other components in the diagram. Then you hit the run button. No compile, no link, none of that. Just Run."
